2 Claims.

This invention relates to a device for transferring ingot mold caps between an ingot mold and a supporting platform.

An object of the invention is to provide a readily portable, rugged and simple device for transferring ingot mold caps in either direction between a mold and a supporting platform.

A further object is .to provide a cap transferrin device which includes a member adapted to bridge the space between an ingot mold and a pouring platform and a trolley riding thereon and adapted to engage a mold cap for carrying the cap in either direction between the mold and the pouring floor.

A further object is to provide a cap transferring device which eliminates the need to use cranes for this purpose, but makes possible the transfer of caps by a simple portable trolley device.

In accomplishing these and other objects of the invention, I have provided improved details of structure, a single form of which is shown in the accompanying drawings, in which:

Figure 1 is a side elevational view, partly in section, showing a portion of an ingot mold and a pouring floor and a cap transferring device constructed according to the present invention in position for engaging or releasing a cap over the mold;

Figure 2 is a view similar to Figure l, but showing the transferring device in position for engaging or releasing the cap over the floor; and

Figure 3 is a top plan view of the cap transferring device.

Figures 1 and 2 show in vertical section portions of an ingot mold l and a pouring platform l2 spaced therefrom. The mold has a cap [3 which commonly weighs in excess of 200 pounds and must on occasion be transferred be-.- tween the mold and the floor. The cap carries a suitable lifting eye [3a.

The transferring device of the present invention comprises an elongated trolley rod M which is adapted to bridge the space between the mold and the pouring platform. Said rod has a shallow U-shaped bend l5, which is situated intermediate its ends and forms a delivery notch, and a sharp bend l6, which is situated adjacent its platform end forms a supporting leg I! adapted to rest on the platform. A handle I8 is rigidly attached to rod I4 adjacent its bend I6. The mold end of rod [4 carries upper and lower longitudinal reenforcing plates l9 and 20 respectively, a U-shaped main yoke 2| and a 2 U-shaped brace yoke 22, all welded together to form a rigid structure adapted to rest on the upper face of the mold. Indexing fingers 23 and 24 are'pivoted to the lower extremities of the main yoke, and have hook portions 25 adapted to engage the edge of the mold.

A trolley 2'6 is mounted on rod I4. The inner end of the upper reenforcing plate I9 is notched to form a stop 21. Trolley 26 can ride along rod l4 between the stop formed by the bend l5 and the stop 21. Preferablythe trolley includes a roller 28, a hook 29 adapted to engage the lifting eye of the mold cap, and a handle 30. Where it is desired to retard movement of the trolley frictionally, the roller can be omitted.

In operation, assume first that it is desired to remove cap I3 from mold If] and transfer this cap to the pouring platform l2. The cap first is loosened in the conventional way. The transferring device just described, which is of light weight and easily portable, is placed across the space between the mold and the platform with the main yoke 2| resting on top of the mold and the hook portions 25 of the indexing fingers- 23 and 24 engaged over the edge of the mold. Handle I8 is lifted manually and trolley 26 moves down trolley rod I4 toward the mold end until it engages stop 21, as shown in full lines in Figure 1. The parts are proportioned so that in this position the trolley is approximately centered over the mold cap I3. Next hook 29 is engaged with the lifting eye [3a of said cap.

Next the platform end of the trolley rod I4 is forced down manually until its leg I! rests on the platform Ill, as shown in dotted lines in Figure 1 and full lines in Figure 2. Trolley 26, carrying cap l3, moves gravitationally along the rod toward said platform until it engages delivery notch l5. The parts are proportioned so that cap l3 now rests on the platform and the transferring device can be removed to be used elsewhere.

When it is desired to transfer a cap from the pouring platform to the mold, the movements just described are reversed. That is, the main yoke 2| and indexing fingers 23 and 24 are engaged with the mold and the hook 29 with the lifting eye of the cap, which now is resting on the platform. Handle i8 is lifted manually and trolley 26, carrying the cap, moves gravitationally down the rod until it engages stop 21. The cap now is centered over the mold. Hook 29 next is disengaged from the lifting eye, and the device can be removed for use elsewhere.

From the foregoing description, it is seen that I do not wish to be limited to the disclosure set forth but only by the scopeof the appended claims.

I claim:

between an ingot mold and a pouring platform comprising an elongated rod having a shallow U- shaped bend intermediate its length, a downwardly depending yoke connected at its upper end to said rod adjacent one end of the latter, the lower end of said yoke being adapted to rest on'the top-of the mold, indexing fingers pivoted to said-yoke adjacent the lower end thereof and adapted to engage over an upper edge of the mold, a leg connected at its upper end to said rodz adjacent the'other end thereof, the lower end ofsaidleg'being'" adapted to rest on the platform,

1. A device for transferring in'gotmolrFcaps between an ingot mold and a pouring'pla'tfor'in comprising an elongated member adapted to bridge the space between a mold-tanda platform,
